TT Electronics has introduced the HPWC (High Pulse Withstand Chip) series of high-energy surge resistors, specifically designed to deliver exceptional surge performance in compact, single-sided flat chip configurations. These resistors are ideal for applications requiring reliable protection and discharge capabilities in small power and control circuits, with a 5% resistance tolerance.
The HPWC family is available in four standard sizes, ranging from 0805 to 2512. They can withstand surge voltages of up to 6.5kV for 1.2/50μs pulses and peak currents of 3kW for 0.1ms pulses. Built upon TT Electronics' PWC (Pulse-Loaded Chip) technology, the HPWC series uses a precision manufacturing process instead of laser trimming to control resistance values. This approach enhances surge performance while maintaining reliability in a single-sided design.
Resistance values range from 1Ω to 100kΩ, with power ratings from 0.25W to 2W. The HPWC resistors are well-suited for input protection in power supplies, circuit breakers, motor drives, and medical monitoring equipment. They are particularly appealing to designers working on compact SMD circuits for power conversion, motion control, and protection systems in industrial and medical applications.
The growing demand for these components is driven by the increasing integration of distributed power management and motion control in industrial and automation systems. At the same time, there's a strong push to reduce size and weight without compromising surge protection, which is essential for meeting EMC compliance and ensuring long-term product reliability.
A key advantage of the HPWC series is its compact footprint, which helps save valuable PCB space. Additionally, the absence of laser trimming eliminates current crowding, reducing hot spots and improving overall reliability. This makes the HPWC series an excellent choice for engineers looking to optimize both performance and design efficiency in their next-generation products.
